Granted: 2007-05-08
Abstract: The plasma spray method produces a material deposit on a substrate to form either a protective coating or a near net shape body, or produces a powder of a given material. The material is supplied to a plasma discharge in the form of a suspension comprising small solid particles of that material dispersed into a liquid or semi-liquid carrier substance. The suspension is brought into the plasma discharge by an atomizing probe using a pressurized gas to shear the suspension and thus atomize it into a stream of fine droplets. The plasma discharge vaporizes the carrier substance and agglomerate the small solid particles into partially or totally melted drops which are accelerated to hit the substrate and form thereon the coating or near net shape body. Alternatively, the molten drops can be solidified in-flight and collected into a vessel to produce a powder of that material.

Title: In-fiber two-stage amplifier providing wdm signal conditioning
Inventor: GUY MARTIN
IPC: H04B10/294
Filed: 1998-04-06
Granted: 2003-11-25
Abstract: The amplifier is a two-stage amplifier in which dispersion compensation and WDM channel equalization are carried out using a plurality of in-waveguide Bragg gratings placed between the two stages. The first stage has a gain able to raise the intensity of WDM optical communications signals to a high enough level that after dispersion compensation and equalization, the signals fed into the second stage nearly or substantially saturate the second stage amplifier. The noise figure signal-to-noise ratio is thereby of good quality since there are no significant losses at the signal input of the signal into the optical amplifier. Erbium-doped optically pumped fiber amplifiers are used for the two stages. An add/drop filter can be appended to the end of the conditioning Bragg gratings. Residual optical signal from the fiber Bragg grating may be used to optically pump another amplifier for amplifying longer wavelength optical signals.

Title: Liquid slurry agitation apparatus
Inventor: BYERS STUART DAVID
IPC: B01F3/12
Filed: 1999-02-10
Granted: 2001-10-30
Abstract: A slurry agitation apparatus for selectively agitating slurry temporarily stored in the interior of a storage tank, which slurry contains heavier-than-liquid solids and is at least somewhat pumpable, comprises a slurry circuit having connected together in seriatim, and in fluid communication through pipes one with the next, an outlet disposed in the sump pit in fluid communication with the interior of the storage tank to permit egress of the slurry therefrom, a flow control valve, a selectively controllable slurry pump, and a discharge nozzle. The discharge nozzle is rotatably mounted in surrounding sealed relation on a substantially vertical spigot securely mounted on the concrete foundation of the storage tank, for selective rotation of the discharge nozzle about a substantially vertical main axis, and has a spout portion in fluid communication with the interior of the storage tank and oriented to emit the slurry from the spout portion as a generally horizontally directed discharge. A hydraulic circuit has connected together in seriatim, and in fluid communication through hydraulic piping one with the next, a selectively controllable hydraulic pump and a selectively operable hydraulic motor mounted within an enclosure located in the storage tank on the foundation, so as to be engaged in driving relation with the discharge nozzle. The discharge nozzle is selectively rotatable about its substantially vertical main axis. When slurry is being discharged from the discharge nozzle, there is a corresponding change in the horizontal direction of the discharge of slurry. The discharge nozzle may be selectively rotated even though a discharge operation is not being carried out; and the discharge nozzle may be stationary for a selected period of time during a discharge operation.
